Compared with the general horizontal pump or vertical sewage pump, the submersible sewage pump obviously has the following advantages:
1. Compact structure and small footprint. Submersible sewage pumps can be installed directly in the sewage tank because they work submerged under the liquid. There is no need to build a special pump room for installing pumps and machines, which can save a lot of land and infrastructure costs.
2. Convenient installation and maintenance. Small sewage pumps can be installed freely, and large sewage pumps are generally equipped with automatic coupling devices for automatic installation. Installation and maintenance are quite convenient.
3. Long continuous running time. The sewage pump is coaxial with the motor, the shaft is short, and the rotating parts are light. Therefore, the load (radial) on the bearing is relatively small, and the life is much longer than the general pump.
4. There are no problems such as cavitation damage and water diversion. Especially the latter point brings great convenience to the operator.
It is precisely because of the above advantages that submersible sewage pumps have been paid more and more attention, and the scope of use has become wider and wider, from the original purely used to transport clean water to various domestic sewage, industrial wastewater, construction site drainage , Liquid feed, etc. It plays a very important role in municipal engineering, industry, hospitals, buildings, restaurants, water conservancy construction and other industries.
